Description

Title of the invention: Gabion with lifting hook Technical field

[0001] The present invention relates to a gabion comprising a cage made of a mesh of metal wires forming a housing for a plurality of stones or pebbles. Prior art

[0002] In the field of construction and exterior design, gabions are well known and have been widely used for several decades. Generally speaking, gabions comprise a wire cage for housing stones or pebbles, ensuring effective and durable support for these stones. Gabions are often used to build retaining walls to delimit levels of different heights. Traditionally, given the large masses of stones housed in the cages, gabions are installed on site with empty cages, then filled by adding the stones on site. This type of installation therefore requires a significant amount of labor and specifically adapted handling equipment. The handling of transporting stones and filling them on site involves significant installation times.

[0003] To avoid these tedious and costly manipulations, different systems have been developed. For example, document EP3214224 describes a gabion comprising a substantially parallelepipedal cage comprising a bottom, two front walls and two side walls, this bottom, these front walls and these side walls being made up of respective lattices which are fixed to each other, two compartmentalizing partitions, which each fixedly connect the side walls to each other inside the cage so that the internal volume of the cage is distributed between two front compartments which are each filled with a filling material comprising aggregates which do not pass through the meshes of the respective lattices of the bottom, the front walls and the side walls, nor through the compartmentalizing partitions so as to be retained inside these front compartments, and at least one lifting partition,which securely connects the front walls to each other inside the cage by extending across each of the front compartments and the intermediate compartment, which, opposite the bottom, is provided with at least one gripping handle.

[0004] Document FR3008113 describes a gabion of parallelepiped shape, consisting of a cage formed of flat metal mesh elements, connected to each other, namely a bottom, four side walls and a cover, and receiving a filling material. pleating. It further comprises: at least one internal lifting panel also consisting of a flat mesh element, and secured to the bottom and to two opposite side walls of said cage, and provided with at least one gripping handle, at least one internal vertical partition or diaphragm, also consisting of a flat mesh element, extending into the internal volume defined by the cage, and secured between two opposite side walls or between a side wall and said at least one internal lifting panel.

[0005] In both of these arrangements, the gripping handles cooperate with a dividing wall provided in the cage. The lifting forces are transmitted to the upper zone of the gabion and result in significant risks of deformation of the cage during a lifting phase.

[0006] To overcome these various drawbacks, the invention provides various technical means. Summary of the invention

[0007] First of all, a first objective of the invention consists of providing a gabion which is easy and quick to install on a construction site.

[0008] Another object of the invention consists in providing a gabion allowing transport in loaded mode, without risk of deformation of the gabion during the lifting phases.

[0009] To do this, the invention provides a gabion comprising a cage made up of a mesh of metal wires forming a housing for a plurality of stones or pebbles, the gabion also comprising a gripping handle, made up of a middle portion extending from the upper zone of the gabion towards the bottom of the gabion as far as under the mesh of wires of the bottom of the cage, and two lateral portions, extending from the base of the middle portion towards the edges of the gabion, under the mesh of wires of the cage, and at least two reinforcing bars, carried by the lateral portions, extending transversely to the gripping handle under the mesh of wires of the cage.

[0010] This embodiment makes it possible to produce a gabion with reduced risks of deformation during lifting phases while the gabion is loaded with stones or pebbles. The safety of site workers is thus better preserved. Due to the absence of a dividing wall, the filling rate is improved. Finally, the manufacture, storage and assembly of the gabion are simplified and costs reduced due to a reduced number of parts.

[0011] According to an advantageous embodiment, the reinforcement bars are fixed to the side portions by welding.

[0012] Advantageously, the gabion also comprises a separating wall arranged transversely between two sides of the cage.

[0013] Preferably, the separating wall cooperates with the gripping handle.

[0014] The dividing wall is advantageously fixed to the cage by a plurality of staples.

[0015] Advantageously, the grip handle and the reinforcement bars are made using steel rods. Brief description of the drawings

[0016] All the details of the embodiment are given in the following description, supplemented by figures 1 and 2, presented solely for the purposes of non-limiting examples, and in which: Fig.l

[0017] [Fig.l] [Fig.l] is a partial schematic representation (with two fewer sides to facilitate visibility of the internal elements of the cage) in perspective of an example of a gabion comprising a gripping handle; Fig.2

[0018] [Fig.2] [Fig.2] shows a section of the gabion of [Fig.l] in front view, cut at cove level. Description of the embodiments

[0019] Figures 1 and 2 illustrate an example of the embodiment of a gabion comprising a gripping and lifting handle allowing a gabion loaded with stones and / or pebbles to be lifted, moved and transported without risk, and without deformation of the metal cage.

[0020] The gabion 1 is designed in a conventional manner, by assembling metal wires to form a mesh of wires 3 making it possible to constitute a metal cage 2 used to house stones and / or pebbles 10. To ensure the lifting function, the gabion is provided with at least one handle 4 of elongated profile. This elongated profile provides a dual function. On the one hand, it allows a portion of the handle to be released above the filling level of the gabion, to allow the handle to be connected to a lifting means. On the other hand, it allows the metal mesh of the bottom of the gabion to be connected to the upper zone of the gabion, so as to exert a lifting force under the metal mesh of the bottom. The handle 4 is in the shape of an inverted “U”, with the rounding in the upper zone of the gabion. The rounding as well as the two edges of this rounding form the middle portion 5 of the handle.The two ends of the "U" are folded and form two lateral portions 6 oriented so as to pass under the metal mesh towards two opposite faces of the cage 2. The folding of the lateral portions 6 is implemented so that the "U" is preferably in a single plane. In the example illustrated, this single plane is arranged centrally to delimit two equal portions of the gabion, so as to allow a lifting action while keeping the gabion balanced. The two lateral portions 6 extend under the mesh towards the edges, with their ends more or . less close to the side faces, depending on the needs and the loads to be supported.

[0021] To ensure perfect distribution of the lifting force and minimize the risks of deformation of the mesh when lifting a loaded gabion, two reinforcing bars 7, cooperating with the lateral portions 6, are arranged so as to extend transversely to the handle 5. By transversely, we mean in a direction forming an angle of between 30 and 90 degrees with respect to the plane formed by the handle. In the example illustrated, the reinforcing bars are perpendicular to the handle and extend towards the other two faces of the metal cage. In the example illustrated, and as clearly visible in [Fig.2], the lateral portions 6 pass under the reinforcing bars 7, so as to properly transmit the lifting force to the reinforcing bars.

[0022] The reinforcement bars 7 are fixed to the lateral portions 6 by any means, for example by welding.

[0023] In an alternative embodiment not illustrated, the gabion also comprises a separating wall arranged transversely between two sides of the cage 2. The wall is for example oriented parallel to the plane formed by the handle, and positioned at a distance or in the immediate vicinity of the handle. In the latter case, the separating wall can cooperate with the gripping handle 4, for example using staples. The separating wall is advantageously fixed to the metal cage by any means, such as for example using staples.

[0024] The grip handle and the reinforcement bars are made using steel rods.

[0025] The middle portion 5 of the handle has a sufficient height to allow the portion in "U" to be accessible when the gabion is filled. [Fig.2] shows the height HA of the handle in relation to the height HG of the gabion. Depending on the case, HA varies between 0.6HG and 1.3HG, and more preferably between 0.9HG and 1.1HG.

[0026] LIFTING METHOD

[0027] The concept as previously described allows the gabions to be manufactured and filled efficiently and safely in the factory, then transported to the site of use, and finally unloaded and positioned in their final arrangement, safely and efficiently, improving productivity, rather than having to place the empty cages and then manually fill the gabions as they are put in place, which is particularly tedious.
